LATCH non VEHICLE noons.

Application filed August 13, 1925. Serial .No. 49,887.

'To all whom it may concern:

Be it known that'I, RICHARD V. KAIMER, a citizenof the United States,residing at New Haven, in the county of New Haven and Stateof'Cdrhlecticut, have invented a acters of reference marked thereon, to bea full, clear, and exact description of the same, and which saiddrawings constitute part of this application, and represent, in

Fig. 1 an inside view of a latch for vehicle doors'constructed inaccordance with my invention.

Fig. 2 a rear view of the same.

Fig. 3 a perspective view of the pushrod lever, detached.

Fig. 4 a perspective view of thelockinglever, detached.

This invention relates to improvement in latches for vehicle doors, andparticularly to latches for this purpose which are provided with meansfor locking the latch-bolt inits thrown position. The object of thisinvention is to provide means for throwing the bolt-holding mechanisminto locked position by means closely adjacent to the means foroperating the latch-bolt, whether" it be a swinging-lever or arotary-sp1ndle,.

, and the invention consists in the arrange ment of two levers, oneoperated by a ver-. tically-arranged push-button to throw the otherlever into locking-engagement with the bolt, the said other lever beingturned out of its locking position by means of the boltoperatingmechanism, and the invention also consists in the construction ashereinafter described and particularly recited in the claims.

In Figs. 1 and 2 of the drawings, I have shown the invention as appliedto a latch for vehicle doors operated by a swinginglever. In carryingout my invention, I employ the usual latch-bolt 10, normally thrownforward by a spring 11, and ada ted to be engaged for rearward movementy a lever 12 extending upward through the door and provided at its upperend with a handle 13. Thebolt is provided with the I usual upwardprojection Mextending into REISSUED thev path of a roll-back 15, whichis adapted to be operated by a handle on the outside,

of the door. Pivotally mounted above the bolt is a locking-lever 16, thenose ofwhichv is adapted to be turned into the path of the I roll-back15. At its rear end, this, lever is formed with a cam-lip 17 adapted tobe engaged by a stud 18 mounted in the lever ally mounted on thecase-plate, above and forward of the locking-lever 16, is a pushbuttonlever 20, formed with a lip 21 adapt-.

ed to bear upon the upper edge of the lockrod 23, which is mounted inthe case close-' ly adjacent to the lever 12, so that it can be operatedfrom the inside of a car.

When it is desired to lock the door in its closed position, the push-rod23 is depressed,

forcing the push-rod lever 20 downward,

causing the lip 21 to engage with the edge 16 of the locking-lever andforceit down,

into the path of the roll-back 15. To move the locking-lever out of itslocked position, the lever 12 is moved rearwardly and the stud 18engages with the lip 17, so as to depress the rear end of thelocking-lever and lift its forward end outof the path of movement of thelower and. At the same time, this upward movement of the locking-leverlifts the push-button lever and with it the push-rod 23, -so that it isin position for relocking the door when desired.

. In Fig. 5 of the drawings, I have shown my invention as ap lied to awell-known form of vehicle door atch, in which the bolt is operated by avertically-arranged, rotatable spindle 24, operated'by a handle 25.

This spindle engages with the'bolt 10 to retire it, and the other partsof the latchmechanism are the same as those above de scribed, exceptthere is no necessity for the '05 and traveling in a segmental slot 19.Pivot I with slots 29 which set over projections '30, which are struckup from the latch-plate and upset to lock the straps in position.

I claim: 7

1. A latch, comprising a bolt, a lever for retiring said bolt, aroll-back adapted to retire said bolt, a locking-lever pivoted above thebolt and extending into the path of the roll-back, a push-rod leverpivoted at one ,end, above and forward of the locking-lever, a push-rodmounted in line with and bearing upon the push-rod lever and adapted,when forced down, to depress the forward end of the locking-lever, andmeans for depressing the rear end of the lockingdever to lift it out ofthe path of the roll-back and to raise the push-rod.

' 2. A latch, comprising a bolt, a swinginglever for retiring saidbolt'forlned with a projection, a roll-back adapted to retire said bolt,a locking-lever pivoted above the bolt and extending into the path ofthe rollback, a push-rod lever pivoted at one end above and forward ofthe locking-lever and adapted, when forced down, to depress the forwardend of the locking-lever, the rear end of said locking-lever extendinginto the path of the projection on the swinging-lever.

3. A latch, comprising a bolt, a lever for retiring said bolt formedwith a projection, a roll-back adapted to retire said bolt, alocking-lever pivoted above the bolt and extending into the path of theroll-back, and into the path of the projection on the bolt-lever, apush-rod lever pivoted at one end and forward of the locking-lever andformed with a lip-adapted to engage with the upper edge of thelocking-lever and with a lip a push-rod in position to engage the saidlip, the rear end of the locking-lever formed with a cam-surface adaptedto be engaged by a projection on the'lever, whereby, when the lever isturned, the rear end of the locking-lever will be depressed andtheforward end lifted out of the path of the roll-back. y

In testimony whereof, I have signed this specification.

RICHARD V. KAIMER.
